'Nature' Apologizes to Swimmer Ye Shiwen for Controversial Article

Nature Apologizes to Swimmer Ye Shiwen for Controversial Article

....The article titled Why great Olympic feats raise suspicions was published on Nature's website on August 1, which says that Ye's gold-winning performance is "anomalous" and implies that her clean drug test during competition can't rule out the possibility of doping.

...Nature's article has been criticized by many scientists, who are the major readers of the journal.

Lai Jiang, a researcher in Pennsylvanian University, commented on the journal's website that the article is so scientifically wrong that it "is a textbook example of what we call 'cherry pick your data'".

Chinese scientists have signed on an open letter to challenge the Nature article.

....."We also regret that the original story included an error about the improvement in Ye's time for the 400-metre individual medley: she improved by 7 seconds since July 2011, not July 2012."

...The author of the article has been criticised for cherry-picking data. Ewen Callaway, a reporter who covers biomedical issues, called Ye's performance at the Olympic Games "anomalous" because she posted a time more than seven seconds faster than at her last major event.

In response to the claim, an associate professor at the University of Kansas, Jun Huan, examined data on more than 2,600 swimmers, covering more than 40,000 performance records between 2007 and 2012. He reached a different conclusion from Callaway.

"For example Stephanie Rice, the 2008 Beijing Olympic 400-metre individual medley gold medallist, improved her performance from the 2007 World Championship to the 2008 Olympic by about 12 seconds. In another example, Kirsty Coventry, the 2008 Beijing Olympic 400-metre individual medley silver medal winner, improved her from the 2007 All-Africa Games to the 2008 Olympic by about 10 seconds," Dr Huan wrote on his website. "We have found half a dozen cases where elite 400-metre individual medley athletes have more than a seven-second performance boost in a year."

Lai Jiang , a doctoral student at the University of Pennsylvania's chemistry department, criticised the comparison of Ryan Lochte's last 50 metres to Ye's as a "textbook example of 'cherry-picking' your data". "Failing to mention this strategic difference, as well as the fact that Lochte is 23.25 seconds faster (4:05.18) than Ye overall, creates the illusion that a woman swam faster than the best man in the same sport," he wrote online.

4. Talk about cherry picking data...

Stephanie Rice and Kirsty Coventry both swam in the LZR Racer, introduced in 2008, a swimsuit now banned from competition due its performance benefits. It's fairly convenient that the professor's analysis starts the year before the new suits were introduced.

Do people really not know that so many of those records that were broken in '08-'09 were due to technological improvements to the swimsuits?

"Going into the {Australian Olympic} qualifiers with bronze medals from the 2007 worlds over both distances, Rice was part of the Speedo sensation. That is to say she was wearing the new outfit, the LZR bodysuit, by the Australian swimwear company that has come under scrutiny due to a tidal wave of world records set by swimmers wearing it."
